6.3.2 Ethernet interface

The pin assignment for Ethernet:

Pin Signal Ethernet Signal

68 FB1 RXN0

69 FB2 RXP0

70 FB3 TXN0

71 FB4 TXP0

72 FB5 not connected

73 FB6 RXN1

74 FB7 RXP1

It is also strongly recommended to keep the length for the signal lines below 30 mm and to take

EMC aspects into account.
